Fecal microbiota transplantation from sodium alginate-dosed mice and normal mice mitigates intestinal barrier injury and gut dysbiosis induced by antibiotics and cyclophosphamide

Abstract

. PICRUSt2 function prediction analysis showed that, compared with the model group, FMT treatment significantly down-regulated lipopolysaccharide biosynthesis and the mitogen-activated protein kinase signaling pathway-fly. Collectively, we found that SA can regulate the gut microbiota structure of normal mice and confirms the effectiveness of FMT in alleviating intestinal barrier damage and gut dysbiosis in antibiotic-cyclophosphamide-induced immunosuppressed mice. This work also reveals that SA can potentially alleviate the immunosuppression caused by cyclophosphamide in mice by modulating the intestinal microbiota and exploiting their functional properties.
